DT 440 or DT 990 Pro 250Ohm unamped?

Hello, so could you please tell me which one sound better if i will not use an amp ? DT 440 (unamped) or DT 990 Pro 250Ohm (unamped) ? In my country (czech republic) they cost DT 440 - 150$ and DT 990 Pro - 185$

Hello, so i was wondering which one is better if i don´t use amp. I was reading a lot about dt 990 and i guess i would need to pay atleast another 100$ for amp to power them up. There is not a lot reviews about dt 440 but they are well known as 'Underrated Headphones'. So what would you recommend me ?
